This Ordnance Survey map shows Brislington as it was some time before 1946. Ordnance survey maps can be a bit confusing because they didn't update everything all at once (this is based on a full revision in 1930, with subsequent additions).
This is from map 156 "Bristol & Stroud" in the New Popular Edition (often referred to as the 6th Edition) of Ordnance Survey maps, at the scale of one inch to the mile (1:63360).
